(a): [H3O+] = 1.0 x 10-5 M at 25°C: what is the OH−concentration? Is the solution acidic, basic, or neutral? A) Acidic B) Basic C) Neutral D) Not enough info to tell. What is the OH− concentration? A) 10-5 B) 10-7 C) 10-9 D) 10-11
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
1.(a): [H3O+] = 1.0 x 10-5 M at 25°C: what is the OH−concentration?
Is the solution acidic, basic, or neutral?
A) Acidic B) Basic C) Neutral D) Not enough info to tell.
What is the OH− concentration?
A) 10-5 B) 10-7 C) 10-9 D) 10-11
Do the calculation:
1.(b):
we assume that they dissociate 100%
Complete the ICE table:
HNO3(aq) + H2O(l) -> H3O+(aq) + NO3−(aq)
I 0.05 (ignore) 0(not really) 0
C
E
What is the pH of the solution?
A) -1.3 B) -1.30 C) 1.3 D) 1.30 E) Cannot determine
1.(c):
Calculate the pH for a 0.10 M solution of C6H5OH (Ka = 1.3 x 10-10). Find the concentration of all species in water and set up an ICE table.
